Abstract
The utility model discloses an unit head bumper shock absorber, include: a connector, the one end of connector is cylindrically, and the other end is outer circumference size and is lighter than six cylindricalitys of cylindrical, and be formed with the hexagonal recess that is used for set stacks, six styletable portions in the cylindrical end of connector portion and be formed with the boss post, cup joint in proper order on the boss post and support the shock pad of making with shock attenuation base and macromolecular material, the outer circumference shape of shock attenuation base and shock pad is the same with the outer circumference shape of six posts. The utility model discloses a purpose -made shock pad absorbs most vibrations, and the vibrations that reduce down -the -hole hammer during operation harm the unit head to guarantee the stability and the life of whole equipment, the utility model has the advantages of easy dismounting, simple structure, small and non -maintaining, the simple effect of practicality has again been reached.
Description
Technical field
This utility model is related to a kind of shock-damping structure, espespecially a kind of unit head connection damping for being matched in down-the-hole drill
Device.
Background technology
The equipment of down-the-hole drilling is referred to as down-the-hole drill, in the down-the-hole drill course of work, is driven by drilling rod by unit head
Down-hole hammer device to hole bed rock stone produces continuous dynamic impact, and this impact causes unit head to be subject to counteracting force, can produce very big
Vibrations, therefore easily cause unit head to damage, need Jing often to keep in repair replacing unit head, reduce production efficiency of equipment, increase
Cost.
Utility model content
In view of at present down-the-hole drill unit head is given a shock problem that is big and being easily damaged in the course of the work, this practicality is newly
Type provides a kind of unit head amortisseur, can greatly reduce such infringement.
The technical scheme in the invention for solving the above technical problem is：A kind of unit head amortisseur, including：Connection
Device, in cylinder, the other end is smaller in size than the hexahedro cylindricality of cylinder in excircle, in the circle of adapter for one end of the adapter
Column end is formed with and is formed with boss post for covering six side's grooves of stacks, hexahedro column end, is covered on the boss post successively
Be connected to the cushion of support damping base and macromolecular material manufacture, the outer circumferential shape of the damping base and cushion with
Hexahedro post outer circumferential shape is identical.
Preferably, the sealing for sealed motive force head tip side is socketed near cushion on the boss post
Circle.
Preferably, the pin-and-hole for positioning is provided with the hexahedro post excircle of the adapter.
Compared with prior art, the beneficial effects of the utility model：This utility model mainly ensureing to be vertically connected with, it is close
In the state of envelope, down-the-hole drill can be coordinated to use the conventional connected mode of drilling rod, absorb most of by special cushion
Vibrations, reduce down-hole hammer work when vibrations to unit head damage, so as to ensure the stability and service life of whole equipment,
This utility model has the advantages that easy accessibility, simple structure, small volume and non-maintaining, has reached the simple and effect of practicality.
Description of the drawings
For the technical scheme being illustrated more clearly that in this utility model embodiment, below will be to needed for embodiment description
Accompanying drawing to be used is briefly described, wherein：
Overall structure diagrams of the Fig. 1 for this utility model preferred embodiment；
Fractionation structural representations of the Fig. 2 for this utility model preferred embodiment.
In figure：1 is adapter, 2 is damping base, 3 is cushion, 4 is sealing ring.
Specific embodiment
Below in conjunction with accompanying drawing and specific embodiment, this utility model is described further.In preferred embodiment
It is cited such as " on ", D score, "left", "right", the term, only understanding for ease of narration such as " centre " and " one ", and be not used to
The enforceable scope of this utility model is limited, being altered or modified for its relativeness is being changed under technology contents, when also without essence
It is considered as the enforceable category of this utility model.
Refer to Fig. 1 and Fig. 2, a kind of unit head amortisseur of this utility model preferred embodiment design, which mainly includes：
Adapter 1, damping base 2, cushion 3 and sealing ring 4.
Specifically, one end of adapter 1 is in cylinder, and, in hexahedro cylindricality, the excircle size of column part is big for the other end
In the excircle size of hexahedro post part, adapter 1 undertakes the connection of unit head and drilling rod.In the hexahedro column end of adapter 1
Boss post 11 is formed with, the cylindrical of damping base 2 and cushion 3, damping base 2 and cushion 3 on boss post 11, is socketed successively
All shapes are identical with the hexahedro post outer circumferential shape of adapter 1, and damping base 2 plays a part of to support cushion 3, cushion 3
Macromolecular material manufacture is adopted as, topmost damping effect is played by cushion 3.
Further, sealing ring 4 is socketed near cushion 3 on boss post 11, sealing ring 4 is to ensure power after connection
Air-tightness between head tip side and amortisseur.
Further, the pin-and-hole 12 for positioning is provided with the hexahedro post excircle of adapter 1.
Further, adapter 1 cylindrical end it is recessed be formed with six side's grooves, this six sides groove be used for connect bore
One end of bar.
During use, six side's grooves insertion of the hexahedro styletable alignment unit head tip side of adapter 1, inserted with latch positioning
Enter pin-and-hole 12；Then, the cylindrical end of adapter 1 is connected to drilling rod using the hexahedro inserting mode of identical, so as to complete connection.
On same down-hole hammer construction equipment, in same operating mode use, this utility model amortisseur is fitted without
Equipment, unit head cause the maintenance cycle for damaging all in 2-3 because shaking, and after being mounted with this utility model damping, it is just few
The problem for occurring causing unit head to damage because of vibrations when down-hole hammer works, the damping effect of unit head are extremely obvious.
The above, is only preferred embodiment of the present utility model, not makees any formal to this utility model
Restriction, any those skilled in the art, in the range of without departing from technical solutions of the utility model, according to skill of the present utility model
Any brief introduction modification, equivalent variations and modification that art is substantially made to above example, still fall within this utility model technical side
In the range of case.
